Weird cramps - scared!

I'm due to start any day now, so it's not weird that I'm having cramps... They are just... Weird.
​Sometimes they are sharp, sometimes dull. Sometimes they are located where my ovaries are, and sometimes they are lower down toward my pubic bone. I even feel slight cramps higher up near my belly button. They are not super painful, just freaking me out by how weird they are.
​I'm 37; had normal pap results as recently as July; had unprotected sex with my fiancé a little less than two weeks ago.
​Sound familiar to anyone?
